I now own 4 of these units. This is probably one of the best flash units ever made, of the non-TTL variety. These are old technology, but very good technology. They utilize a simple photo sensor for exposure, with thyristor circuitry to conserve battery power. I use them on Nikon D80's and they do a bang up job with lots of light and pretty consistently accurate exposures. They can be fooled into a bad exposure by an unusually bright of dark subject, but I suspect a TTL flash could have the same issues. Since the head is off axis to the lens by design, you get a pretty nice lighting when mounted to the camera, and better lighting when held off camera. I used the predecessor, Sunpak 611, for many years back in my pro days. It was a great unit as well, but had too high a trigger voltage for the new cameras. BTW, I have also rebuilt/replaced the original cells in the rechargeable batteries with Ni-Mh 3800mah cells that are FAR superior to the original Ni-Cad 1200mah cells. Great recycle times for a long time. The next closest thing to these units would be a Quantum rig, at a much higher price.Read full review
A super flash with great power and tremendous coverage of the subject. The power ratio control is vital as can treak the power up to 1/128 in manual to cover any lighting situation. I am able to get perfect exposures as close as 6 inches without using a ringlight with the power ratio control. The zoom head is great as can go from wide angle to normal to tele as needed. Flash is heavy but balances well a solid camera. The guide number and power ratio control are very accurate. The tilt and swivel head is another vital feature.
What on earth is steveelaine4 talking about? These reviews are to rate the item, not rate the condition yours is in. Duh. That is what feedback is for, nub. The 622 is supposedly the most powerful handle-mount flash available. As far as I can tell, that claim is accurate. It's big, it's heavy, it's powerful. If you are using C-cells, good luck...you arent going to get a tremendous amount of full-power flashes with those. This flash does best when powered by a Turbo or Lumedyne battery. It's a bit flimsy, so dont expect to drive nails with it like you could with a Metz flash. Overall, its a lot of flash for a fraction the price of some of the other nearly-as-powerful flashes. (This thing puts out as much as a smaller monolight).
Well made handle mound flash unit that is versital as well. The re-chargeable battery lasts long and recycles quick. It is a big unit though, quite heavy and the battery can get in the way of some mounts. However, there are several flash heads that can be used for a versital lighting unit. A lot of power for the money. Optional power sources are available too, like Quantum, to make it even more versital. I plan to get the Bare Bulb head for other lighting uses.
This is a great flash. I've owned one for over 20 years. I does go through batteries so I would recommend an external power source. I use a quantum turbo with mine. It has some real power too. I've taken shots in dark rooms at over 50 feet that came out amazing. It is reliable, and tough. Cons: It is heavy, especially if you use the C battery pack.
